In the title compound, [Cu2(C11H13N3O3S)2(C2H6OS)2], the CuII cation is N,N′,O-chelated by a deprotonated hydroxyimino-tosylhydrazone ligand and coordinated by a dimethyl sulfoxide molecule. One O atom from the adjacent hydroxyimino-tosylhydrazone ligand bridges the CuII cation, forming the centrosymmetric dimeric complex. The cation is in an overall distorted N2O3 square-pyramidal coordination environment. The methylbenzene ring is twisted with respect to the hydrazine fragment, with a dihedral angle of 89.54 (9)° between the planes. An intramolecular C—H
O hydrogen bond occurs. In the crystal, molecules are linked by weak C—HO and C—HS interactions. Weak π–π stacking is also observed between parallel benzene rings of adjacent molecules, the centroid–centroid distance being 3.9592 (17) Å.

In the title compound, C14H13ClN4S, obtained from a reaction of 2-benzoyl-4-chloroaniline with thiosemicarbazide in ethanol, the dihedral angle between the aromatic rings is 81.31 (13)°. In the crystal, the molecules are linked by three N—HS hydrogen bonds, forming centrosymmetric rings with set-graph motif R22(8) and R22(18), and resulting in the formation of a two-dimensional network lying parallel to (010).
